What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
What is the circumference of a 35 ft diameter circle?
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 35 feet, so the circumference would be C = π(35) = 110.19 feet.
What is the area of the circle whose equation is (x - 9)2 (y - 3)2 64?
The 64 is equal to the radius squared. Therefore, 8 is the radius and the 9 and 3 are the coordinates of the center. Area of a circle is Pi * radius squared. In this case that is 64 times pi. or approximately 201.062
What is the area of a circle with a diamter of 16cm?
64 pi ie just over 201 sq cm
What is the approximate area of a sector with radius equal to 8 and measure of arc equal to 300 degrees?
The area of the full circle is (pi) R2 = 64 pi.We call a full circle "360 degrees".The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is(5/6) x (64 pi) = 167.55 square units (rounded)
